In the world sloth calls itself tolerance; but in hell it is called despair. It is the accomplice of every other sin and their worst punishment. It is the sin that believes in nothing, cares for nothing, seeks to know nothing, interferes with nothing, enjoys nothing, loves nothing, hates nothing, finds purpose in nothing, lives for nothing and remains alive only because there is nothing it would die for. (Dorothy L Sayers, from, I think, the essay The Other Six Deadly Sins in The Whimsical Christian)
